Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Secure the vehicle with jack stands to ensure stability.

3. Inspect and Replace Components

Shock Absorbers/Struts
- Remove the wheel to access the suspension components.
- Unbolt the top and bottom of the strut using a socket set.
- Replace the strut with a new one, ensuring it is properly aligned.
- Torque the bolts to manufacturer specifications (typically around 40-50 ft-lbs).
- Repeat for the opposite side if necessary.
Sway Bar Links
- Locate the sway bar link and check for any wear.
- Remove the sway bar link by unbolting it from the sway bar and the control arm.
- Install the new sway bar link and torque it to specifications (usually around 20-25 ft-lbs).
Ball Joints
- If ball joints are worn, remove the control arm by unbolting it from the vehicle.
- Use a ball joint separator tool to remove the old ball joint.
- Install the new ball joint and reattach the control arm, torquing the bolts to specifications.

4. Reassemble

Reattach the wheel and lower the vehicle back to the ground.
Reconnect the battery.
